Few topics in family law generate as much confusion — and misinformation — as child support. Whether you’re going through a divorce, a custody dispute, or a modification hearing, you’ve probably heard advice from friends, family, or the internet that sounded authoritative but may have been completely wrong.
In South Carolina, child support in South Carolina is governed by specific statutes and guidelines. The state uses an income shares model, which calculates support based on both parents’ combined gross incomes and the number of children. While the formula provides a framework, there are numerous factors and exceptions that the average person doesn’t know about.
Let’s separate fact from fiction. Here are the five most common child support myths in South Carolina — and the truth behind each one.
Myth 1: “Mothers Always Get Child Support”
The Truth: South Carolina’s child support system is gender-neutral. The obligation to pay child support is based on income and custody arrangements — not on whether you’re the mother or the father.
Under the SC Child Support Guidelines (SC Code § 63-17-470), the court calculates each parent’s proportional share of the child’s financial needs based on their gross income. The parent who does not have primary physical custody typically pays support to the custodial parent — regardless of gender.
In practice, this means:
- If the father has primary custody, the mother may be ordered to pay child support
- If both parents earn similar incomes and share custody equally, the calculation may still result in a support obligation for the higher-earning parent
- The court considers the actual financial needs of the child, not outdated assumptions about gender roles
We’ve seen a significant increase in cases where fathers receive child support in Columbia and across South Carolina. The law treats both parents equally.
The Fact: Either parent — mother or father — can be ordered to pay child support. The calculation is based on income and custody time, not gender.
Myth 2: “If I Have 50/50 Custody, I Don’t Pay Child Support”
The Truth: Having equal parenting time does not automatically eliminate a child support obligation. This is one of the most widely believed — and most incorrect — myths about child custody in SC and child support.
South Carolina’s child support guidelines include a shared custody adjustment for situations where each parent has the child for at least 109 overnights per year. However, the adjustment modifies the calculation — it doesn’t eliminate it.
Here’s why: The child support formula accounts for the income disparity between parents. If one parent earns $120,000 per year and the other earns $45,000, the children’s standard of living should be consistent in both homes. Even with a 50/50 schedule, the higher-earning parent will likely owe some level of support to ensure that the child’s needs are met regardless of which home they’re in.
When 50/50 Custody Might Mean No Support:
If both parents have roughly equal incomes and equal parenting time, the calculated support obligation may be minimal or even zero. But this is the exception, not the rule.
The Fact: Equal custody time reduces the support amount but rarely eliminates it entirely. Income differences between parents are the key factor.
Myth 3: “Child Support Automatically Ends When My Child Turns 18”
The Truth: In South Carolina, child support does not automatically end on a child’s 18th birthday. The actual rules are more nuanced:
- Child support continues until the child turns 18, unless the child is still enrolled in high school — in which case support continues until graduation or age 19, whichever comes first.
- Support may end earlier if the child is emancipated, gets married, or enters active military service.
- Support obligations do notautomatically terminate. The paying parent must typically file a motion with the court to formally end the obligation. Simply stopping payments without a court order can result in contempt charges and accumulated arrears.
What About College?
Unlike some states, South Carolina does not require parents to pay for college expenses through child support. However, parents can voluntarily agree to contribute to college costs in a separation agreement, and the court may approve such agreements. If college support is important to you, it should be addressed during your divorce or custody negotiations.
The Fact: Child support can extend beyond age 18 if the child is still in high school. Always file a motion to formally end your obligation — don’t just stop paying.
Myth 4: “I Can Withhold Visitation If They Don’t Pay Child Support”
The Truth: Absolutely not. In South Carolina, custody and child support are legally separate issues. One parent’s failure to pay support does not give the other parent the right to deny visitation or custody time.
This is one of the most dangerous myths because acting on it can backfire severely:
- You could be held in contempt of courtfor violating a custody order
- The judge may view you as the uncooperative parent, which could affect future custody decisions
- You could be ordered to pay the other parent’s attorney’s fees
What to Do Instead:
If your co-parent isn’t paying court-ordered child support, the proper remedy is to:
- File a contempt actionwith the family court, asking the judge to enforce the support order
- Contact the South Carolina Department of Social Services (DSS)Child Support Enforcement division, which can garnish wages, intercept tax refunds, and take other enforcement actions
- Talk to your attorneyabout your options for enforcement
The court takes non-payment of child support seriously. Consequences can include wage garnishment, license suspension (driver’s, professional, and recreational), passport denial, and even jail time for willful contempt.
The Fact: Never withhold visitation as punishment for non-payment. Use legal enforcement mechanisms instead — they’re more effective and won’t put your own custody at risk.
Myth 5: “Child Support Amounts Are Set in Stone”
The Truth: Child support orders in South Carolina can be modified when there has been a substantial change in circumstances. Life doesn’t stand still after a divorce, and the law recognizes that.
Common reasons for child support modification include:
- Significant change in either parent’s income— a job loss, a promotion, a career change, or a new business
- Change in custody arrangements— if the child begins spending significantly more time with one parent
- Change in the child’s needs— such as developing a medical condition, starting private school, or requiring special services
- Change in the number of children— if the paying parent has additional children from a new relationship (though this doesn’t guarantee a reduction)
- Incarceration— under certain circumstances, incarceration may qualify as a change in circumstances
How to Request a Modification:
To modify child support in South Carolina, you must:
- File a petition with the family court (SC Code § 63-3-530)that issued the original order
- Demonstrate a substantial and material changein circumstances since the last order
- Provide updated financial documentation (income, expenses, tax returns)
The court will recalculate support using the current guidelines and adjust the order accordingly. You cannot unilaterally reduce your payments — any change must be approved by the court.
The Fact: Child support can be modified up or down. If your circumstances have changed, don’t ignore the issue — file a modification petition.
Frequently Asked Questions About Child Support in SC
Q: How is child support calculated in South Carolina? SC uses the income shares model, which combines both parents’ gross incomes, applies the guidelines worksheet, and divides the obligation proportionally based on each parent’s income share.
Q: Can child support be waived by agreement? No. Parents cannot waive child support because it is the child’s right, not the parents’. The court must approve any child support arrangement, and it must meet the guidelines unless there’s a documented reason for deviation.
Q: Is child support different from alimony in South Carolina? Yes. Child support is for the financial needs of the children. Alimony (spousal support) is for the financial needs of a former spouse. They are calculated differently and serve different purposes.
